The equilibrium constant for the reaction A(g) B(g) is Keg = 1.2 x 103. %3D 1) Based on the value of Keq, at equilibrium [ Select ] 2) At equilibrium [A] = 0.015M. What is the concentration of B at equilibrium? [ Select ] 3) If more B is added to the reaction vessel, which direction will the reaction equilibrium shift? no shift will occur

For a reaction A+B 2 AB, if the initial concentration of A is 2.00 M, B is 1.80 M and AB is OM and the equilibrium concentration of AB is 0.02 M. Select all statements that are TRUE. O The concentration of A at equilibrium is 2.00 M. O To calculate the Keg for this reaction, we can use (A]=2.00 M, [B]= 1.80 M and (AB]=0.02 M to solve for it. O The concentration of B at equilibrium is 1.78 M. O The Keq will be much larger than 1 and this reaction favor the formation of the product. O The change in concentration, x, is equal to 0.02 M.
